go-hubspot

Unofficial Go client for the HubSpot API. hubspot.NewClientWithResponses("https://api.hubapi.com", ...) from github.com/psyb0t/go-hubspot gives a typed method for every path in HubSpot's unified OpenAPI spec (721 paths), including CRM objects such as contacts, companies and deals, associations, properties, search, marketing, CMS, automation, conversations, files and webhooks. Auth is a Bearer private app or OAuth access token set through a request editor. Responses decode into typed JSON200/JSON201 fields. Use when Go code needs to read or write HubSpot data, or already imports go-hubspot.

Typed Go client for the HubSpot API, generated with oapi-codegen. The package is hubspot; every endpoint is a method on *hubspot.ClientWithResponses.

For install details, naming, more operations and the developer API key scheme, see references/setup.md.

Security & safety

• Read the access token from an environment variable such as HUBSPOT_ACCESS_TOKEN. Never hardcode it, commit it or log it, and never print request headers.
• The client talks only to the base URL you give it. Use https://api.hubapi.com; HubSpot data goes nowhere else.
• Create, update, merge, archive, delete and GDPR purge endpoints change a live HubSpot account. Call them only when the user asked for that change, and only on records the task owns.

When to use

• Go code needs to read or write HubSpot CRM records, associations, properties, marketing, CMS or other HubSpot API data.
• You want typed request and response structs instead of hand-written HTTP calls.
• The project already imports github.com/psyb0t/go-hubspot.

When NOT to use

• The code is not Go. Use one of HubSpot's own SDKs.
• You need an endpoint outside HubSpot's unified spec, such as a legacy v1 API. The client has no method for it.
• You only need to receive HubSpot webhooks. The client sends requests; it does not run a webhook server.

Usage

go

import (
	"context"
	"net/http"
	"os"

	"github.com/psyb0t/go-hubspot"
)

auth := hubspot.WithRequestEditorFn(func(_ context.Context, req *http.Request) error {
	req.Header.Set("Authorization", "Bearer "+os.Getenv("HUBSPOT_ACCESS_TOKEN"))

	return nil
})

client, err := hubspot.NewClientWithResponses("https://api.hubapi.com", auth)
if err != nil {
	return err
}

Read one contact (GET /crm/objects/2026-03/contacts/{contactId}):

go

props := []string{"email", "firstname"}

res, err := client.Getcrmobjects202603contactsContactIdGetByIdWithResponse(
	ctx,
	"101",
	&hubspot.Getcrmobjects202603contactsContactIdGetByIdParams{Properties: &props},
)
if err != nil {
	return err // transport or decode failure
}

if res.JSON200 == nil {
	return fmt.Errorf("hubspot: %s: %s", res.Status(), res.Body)
}

fmt.Println(res.JSON200.Id, res.JSON200.Properties["email"])

Create a contact (POST /crm/objects/2026-03/contacts, answers 201):

go

res, err := client.Postcrmobjects202603contactsCreateWithResponse(
	ctx,
	hubspot.CrmObjectsSimplePublicObjectInputForCreate{
		Associations: []hubspot.CrmObjectsPublicAssociationsForObject{},
		Properties:   map[string]string{"email": "[e-mail]"},
	},
)
if err != nil {
	return err
}

if res.JSON201 == nil {
	return fmt.Errorf("hubspot: %s: %s", res.Status(), res.Body)
}

Search contacts (POST /crm/objects/2026-03/contacts/search):

go

value := "[e-mail]"

res, err := client.Postcrmobjects202603contactssearchDoSearchWithResponse(
	ctx,
	hubspot.CrmPublicObjectSearchRequest{
		FilterGroups: []hubspot.CrmFilterGroup{{
			Filters: []hubspot.CrmFilter{{
				PropertyName: "email",
				Operator:     hubspot.CrmFilterOperatorEQ,
				Value:        &value,
			}},
		}},
		Limit:      10,
		Properties: []string{"email"},
		Sorts:      []string{},
	},
)

err is only set for network, request building or JSON decode failures. A HubSpot error status still returns err == nil: check res.StatusCode() or that the matching JSON2xx field is non-nil, and read res.Body for the error payload.
